the IPCC team made it clear in their May report that it was not only feasible to make these changes but economically possible as well. They calculated that if we made this energy transition, the economy would grow very slightly more slowly than before -- about 0.12 percent more slowly annually, or 3 percent total by 2030. In other words, our children would have to wait until Thanksgiving 2030 to be as rich as they would otherwise have been on New Year's Day of that year.
